SAFETY-RAZE.

To all whom t may concern:

Be it known that l, HELIER ALEXANDRE VINCENT, a Britain, residing at No.20 Sydenham Hill, in the county of London, England, have 1nventedcertain ,new and useful improvements in. a new or lmproved Safety-Razor,of which the following is a specification;

The present invention relates to a known construction of safety razor inwhich the blade is held in position against an overhanginglip orstop orr`lips or stops on a somewhat tray shaped'holder proper by pressurecaused by the inner end of the handle when ity is screwed or tted intoor secured to the said holder proper. According to the said inventionthe said pressure is exerted through the medium of a resilient membercarried by the inner end 'of the handle whereby the razor blade issecuredv in position without danger of injuring the blade and also witha kmaximum of simplicity of the parts thus facilitating cleanliness.Theaforesaid resilient membenis preferably a spring mounted pin workingaxially within the handle. lt is also preferred to provide means such asa stem on the back of the blade projecting through the rear of theholder proper for preventing side movement of the blade and when a stemas aforesaid is employed for this purpose it is preferably arranged tobe operable by the thumb or linger whereby the razor blade may be turnedup from the guard so that the razor blade and holder may be e'ectivelywashed without removing the blade from the holder.

The said invention is hereinafter more particularly described withreference to the accompanying drawings which illustrate the preferredembodiment thereof.

Figure l of the .sa-id drawings is a side view of the device, Fig. 2 arear View thereof,`Fig. 3 a Yfront view, Fig-4 a plan, Fig. 5 a sectiontaken on the line A A Fig. 2, Fig. 6 a section# taken on the line B BFig. 2 and Fig. 7 aside view showing the razor blade turned up from` heguard under thumb pressure as hereina ter described.

In the following description the parts of the said drawings are referredto by the letters marked thereon the same reference letters indicatingthe same or like partsin all the said figures.`

a' is the holder proper which at its fore end a 1s toothed to form theguard and at its Specification of Letters Patent.

Application filed July 24, 1917. Serial No. 182,455.

rear part a2 is of curved shape terminating at a3 toward the fore partina middle somewhat pointed overhanging part. is the .safety razor bladewhich has a stem b at the rear which when the said blade is in theholder a protrudes to the rear through a slot at therein. The guard a isslightly recessed on the side nearer the razor blade l) so ythat whenthe latter is in position it bears on the end portions of the guardonly, leaving a slight space between the guard `and razor blade foralmost the-whole of the length of the blade. c is the handle which istubular and screwed into the holder proper a. The said handle hasmounted within it at its inner end a pin d which is resiliently pressedoutwardly by thehelical spring c `within the handle which 4spring isretained the holder af is of course prevented by thek position of thestem b in the slot at. By examining the accompanying drawings, it willbe observed that the stop a3 is nearer the guard a than the part wherethe pin d bears on the razor'blade b. To securethe razor blade b in theholder/proper a the handle C being separate from the said holder it Visonly necessary to place the razor blade in the holder proper a so thatits stem is inthe slot a4 and the edge of the razor blade approximatelycoincident with the fore edge of the guard a', then to screw the handlec into the holder proper a whereupon the pin d b ea'rs against the razorblade and'lifts it until it bears against the stop as against theresilience of the spring a. rll`he handle c having been screwed homethe' razor blade b '1s securely gripped between the pin ci and the stopa3 and the relative positions hereinbefore explained of the said pin andstop are such that while the said handle o is being screwed home andthe'pressure of the pin loo onl the razor blade bgradually increasedthev )i said .blade 1s caused thereby automatically l and readily toassume the correct shaving angle and correct shaving position in "relaftion to the guard a. By pressing. on e or linger the razor blade b maybe lifted protruding part of the stem b bythe thumb from the guard aagainst the resilience of the spring c as illustrated 'in Fig. 7 wherebythe holder proper a and razor blade b may otherIv means may be providedfor the purpose such as lips at each side of the rear part ot' theholder proper a. This alternative is employed in cases where the razorblade is not provided with a stem as here v inbefore described.

The invention is not only applicable to devices in which the handle isscrewed into 'the razor holder proper but is applicable to devices inwhich the handle is secured by other means as for example a bayonetjoint..

What I claim and desire to secure byJLetters Patent of the United Statesis l 1. A safety razor com rising a holder for the razor blade, an overanging stop thereon, a handle and a resilient member carried by theinner ena of the said handle which bears against the inner surface ofthe blade at a part to the rear of the said stop to ref handle is inplace bearing on the inner surface of the blade at apart `to the rear ofthe said stop to resiliently press a part of the outer surface of theblade, nearer the edge, against the said stop.

3. A safety razor comprising a holdcr for the razor blade, anoverhanging stop thereon, a handle the inner end of which screws intothe said holder proper, a resilient me'nber carried by the inner end ofthe said handle between which and the said stop Vthe razor blade is heldin position by the holder proper, a stem on the back of the razor bladeand an aperture in the rear of the said holder to receive said stem andallow the' razor blade to be tilted on the said stop and its edge partlifted from the guard, for the purpose set forth.I
